this article helpful in explaining the declining cost of health care:
We have done it. We have decreased the increase in the cost of health care. Let us explain. For three decades (1980-2009), the cost of health care has been increasing each year at an average rate of 7.4 percent -- double the rate of inflation. However, over the past three years, the increase in health care expenditure has remained at a low 3.1 percent. Is this decline the desperately-needed bend in the health care cost curve, or just the impact of the depressed economy?
